Application filed June 28, 1926.

wire or the like. with their heads when the wire is in a low position such as in low parts of mines, tunnels and the like.

Another object of the invention is to provide means for clamping the guard to the wire itself so that the device can be readily put in place and without the necessity of boring holes in the roof of the tunnel to receive supporting means for the guard.

This inventiom also consists in certain other features of construction and in the combination and arrangement. of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing our invention in detail, reference willbe had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and. in which 2- Figure l is a perspective view of a guard showing the same in use.

Figure 2 is a longitudinal sectional view.

AFigure 3 is a section on line of Figure 2.

ln these views7 l indicates an inverted trough-shapedmember which may be made of any suitable` material but which is preferably formed of canvas with arubber coating and which has reinforcing bands 2 extending transversely thereof -and fastened thereto by rivets The device must be stitt enough to prevent bending when struck by the head or other partA of the body of a person.

Bolts et are carried by those portions of the device which are reinforced by bands and each bolt is insulated from the device by means of the insulation, shown at Each bolt carries a pair of clamping plates 6 by having itsvhead 7 engaging slots in the plates, the plates being held in clamping position on the trolley wire A by the bolts S` Serial No. 119,146.

which pass through the plates. A Washer 9 may be placed on the bolt between the lower part of the insulation and the. tops of the plates.

From the foregoing, it will be seen that the trough-shaped member is supported in inverted position from the top of the trolley wire so that the edges of the device extend downwardly below the wire and will thus preventa persons head from coming against the wire as the lower edges of the device would be engaged by his head and thus prevent Contact with the wire.

rlhe device can be easily and quickly attached to the trolley wire and by exercising a little care, the device can be attached to the wire without lturning oif the current. The device can be reinforced, if necessary or (ilesirable, to prevent the edges of the member being forced upwardly by the head of a person striking the same.

The device can be made of Vany desired size so that it will cover those portions of the wire which are so low that they might be struck by the head of a person passing under them.

trough shaped men'ibcr, bolts passing through the center of the member and depending into the same, means for insulating the bolts from the member, a pair of clamping plates carried by each bolt, said plates having slots therein for receiving the heads of the bolts, and bolts for clamping the plates on a wire.

` In testimony whereof we affix our signatures.
